Are there any $_POST variables that are sent with my transaction complete url, that I can save in the users session. I would like to be able to capture the email address from the customers PayPal account.

@danlefree Hi, I am going to use my IPN to save to the database but I would like to pull this information from the database and display it back to the customer. I think I have found a solution. I guess I can save the users IP address to the database, and then search for this when they reach the transaction complete page on my site.
